BAG-CLEANING APPARATUS.

Specification of Letters Patent.

Patented Dec. 5, 191 6.

Application filed August 2a, 1916. Serial No. 117,179.

To all whom it may concern Be it known that I, Jonx M. KELLY, a citizen of the United States, and resident of Manitowoc, in the county of Manitowoc and State of IVisconsin, have invented certain new and useful Improvements in Bag- Cleaning Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof.

Particularly-with respect to cement bags,

considerable difiiculty and inconvenience is attendant upon removing therefrom those portions of the contents-which chug. to the sides of the bags when they are emptied.

It is for various reasons desirable to re-.

move all of the contents of the bags be ore shipping them, and it is therefore the object of the present invention to provide an apparatus whereby a plurality of bags may be quickly and thoroughly cleansed of those portions of their contents which tend to cling therein when the bags are initially emptied,

and it is more specifically an object to provvide an apparatus wherein the bags are sub jected to oscillation, and to the simultaneous passage of a current of air therethrough.

With the above and other objects andadvantages in view, the invention resides more particularly in the novel combination, arrangement and formation of parts more particularly hereinafter described and particularly pointed out in the appended claims.

In the drawings Figure 1 is a vertical sectional view through a bag cleaning apparatus constructed in accordance with the present invention. Fig. 2, is a transverse sectlonal View through the apparatus, as indicated by the line 2-2 of Fig. 1. Fig. 3 is a transverse sectional view through a portion of the apparatus, and showing a modified form, of'bag support, the plane of this view being indicated by the line 3-3 of Fig. 2.

Referring now more particularly to the accompanying drawings, there is provided a casing 5 which is supported by the legs (3 and which is provided with a dished bottom 7 havihg its central portion merged into a horizontally extending neck 8. The top of the casing is provided with a removable cover 9., For supporting a plurality of bags 'in this=casing, there is provided a rectangular frame 10 disposed horizontallyin the lower portion thereof and slidably mounted on inwardly extending bracket ii ges 11 carried by the casing and a plurality of upstanding bag-supporting members 12 of 1nof retractile springs 13 are secured to oneend of the casing and to depending ears l-l on'the sides of the frame. Journally mounted at said end of the frame is a vertical shaft 15 and this shaft carries a trip cam 16 which is engage'able by a roller carrying projection 17 of the said frame 10. Thus rotation of the shaft 15. will procure oscillation of the frame 10 and it is noted that as the trip lever moves past the roller-carrying projection 17, the springs 13 will impart a violent jerking movement to the frame, to materially assist in dislodging particles of contents from bags held on the members 12. For driving this shaft 15, a transversely disposed stub shaft is journaled at the upper portion of the casing and is provided with a crank handle 1!) and witha beveled gear 20 connecting with a relatively smaller beveled gear 21 on the shaft 15. j i

For creating a current of air in the easing, simultaneously witl-i'oscillation of the bag supporting members, an angular spout 22 extends from the "neck 8, 'with its discharge end directed downwardly and adapt ed for attachment of a bag A thereto. Ex-

tending through the horizontal portion of the spout is a-shaft 23 carrying a fan 24:,

taneous oscillation of the bag supporting.

members and suction at the "bottom of the casing, whereby the ctmtents of the bags are jarred loose and conveyed through the spout 22 at the bottom of the easing, into the bag A, thus effectively cleaning the bags.

In Fig. 3, a slightly modified structure is shown wherein the bag supporting members, designated at 12 are formed of coiled lengths of wire bent in inverted U shape,

and secured on the frame 10 by engagement of upstanding projections 28 carried by said frame in the end of their legs, this arrangement obviously procuring a greater degree of oscillation of the bag supporting members in view of the resilient flexibility of the coils.

I claim:

1. A bag cleaning apparatus comprising an oscillatory frame, means for oscillating said frame and bag supports carried by the frame and comprising coils of wire bent to form bag holding frames.

2. A bag cleaning apparatus comprising an oscillatory frame, bag supports comprising lengths of coiled wire bent in inverted U shape, upstanding projections on the frame engageable in' the free ends of the arms of said lengths of coiled wire, and means for oscillating the frame.

3. A bag cleaning apparatus comprising a casing, an oscillatory frame mounted in the lower portion of the casing, a vertical shaft journaled on the casing, a stub-shaft,

the side of the casing, a stub-shaft journaled on the casing, a crank handle on. the stub shaft, intermeshing gears on all the shafts and means carried by the vertical shaft for oscillating the frame.

In testimony that I claim the foregoing I have hereunto set my hand at Manitowoc. in the county of Manitowoc and State of Wisconsin, in the presence of two witnesses.
